Official title: Duke APOL1 Research Biorepository

Run by Duke University · NCT04160507 · Data updated 2026-11-12

This study is trying to understand how certain genetic changes in the ApoL1 gene affect kidney disease in people of African ancestry by collecting samples from those with and without kidney problems.

Is this trial a fit for you?

Likely a good fit

Ideal candidates include self-identified African Americans, Afro-Caribbean individuals, and other black individuals with varying stages of kidney disease or healthy black adults aged 50 and older with no known history of kidney disease.

Probably not a fit

Patients with diabetic nephropathy or healthy controls with any form of kidney disease may not benefit from this study.

What this trial studies

The Duke ApoL1 Nephropathy Biorepository focuses on understanding end stage kidney disease (ESKD) by collecting samples from individuals with and without kidney disease, particularly those of African ancestry. This observational study aims to explore the genetic factors, specifically mutations in the ApoL1 gene, that contribute to the higher prevalence of kidney failure in this population. By utilizing advanced techniques to create kidney-like cells from induced pluripotent stem cells (iPSCs), researchers hope to uncover the mechanisms linking these mutations to kidney disease. The study will include both affected individuals and healthy controls to provide a comprehensive understanding of the condition.

Why it matters

Potential benefit: If successful, this research could lead to improved understanding and treatment options for end stage kidney disease in populations affected by ApoL1 mutations.

How similar studies have gone: While this approach is innovative, similar studies have shown promise in understanding genetic contributions to kidney disease, particularly in populations with specific genetic backgrounds.
